Professor Ulrich Trottenberg, head of Fraunhofer Institute for Algorithms and Scientific Computing SCAI that co-ordinates the SIMDAT project describes the demonstrator's objectives as "to demonstrate that the technologies developed in SIMDAT allow all parties involved in the functional design of cars to access and leverage product development data across distributed locations and disciplines."
The demonstrator supports the demand of automotive engineers to correlate data from simulation with data from physical test, also known as CAE (Computer Aided Engineering) and CAT (Computer Aided Testing) data. Today, the data resulting from simulation, and test processes are stored in separate data management systems with heterogeneous data models, without common interfaces. This makes data correlation a tedious and error-prone task. The CAE-CAT integration demonstrator developed by the SIMDAT Automotive Activity partners AUDI AG, MSC.Software and ontoprise GmbH integrates this heterogeneous data from CAE and CAT via ontologies with SIMDAT Grid technologies ensuring secure communication. While SIMDAT Grid technologies ensure the seamless access of remote data sources the use of semantic technologies assures the seamless integration of heterogeneous data models. The demonstrator has successfully proven the value-add of the combination of the two technologies.
"The CAE-CAT demonstrator proves the leading-edge achievements of the SIMDAT project," explains Senior Manager Dr. Stefan Mayer (MSC.Software). "Within Audi's CAE data and process management system MSC SimManager three real use-cases were defined: user navigation, curve comparison and comparison reporting." The key accomplishment is that the user is now able to view and use CAT data - resulting from physical test - in the same manner as CAE data, extracted by a virtual simulation. The user can even compare mixed data from both CAE and CAT. MSC SimManager acts as aggregated visualisation platform to provide a graphical user interface. Users can easily navigate through CAE simulations and CAT experiments and access corresponding data like curves, movies, values and pictures.
Today, the growing competition in the automotive industry requires continuous reduction of development and innovation cycles while the demands on quality, safety and comfort are increasing. "Advances in CAE, CAD and CAT technologies and processes have contributed significantly to the ability of the automotive industry to keep up with these requirements," summarizes Audi's Head of CAE Methods, Dr. Karl Gruber. "The SIMDAT CAE-CAT integration demonstrator was developed to meet these challenges, and Audi will evaluate its usable industrial solutions and competitive advantage for the automotive application area."
SIMDAT has received research funding by the European Commission under the Information Society Technologies Programme (IST), contract number IST-2004-511438. Maximum Community contribution to project: 11 Mio Euro, Project start: 1 September 2004, Duration: 48 months, Partners involved: 27. The project is coordinated by the Fraunhofer Institute SCAI in Sankt Augustin, Germany.AUDI AG

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
